In general, interior steelwork is exposed to less severe conditions than exterior, but in some chemical factories the reverse is true and here special types of paint are needed. Much structural steel is encased in concrete it is therefore hidden from view and is given some protection while the concrete remains alkaline. Where the concrete is thick, corrosion may be delayed, but as the concrete becomes carbonated and particularly if it is penetrated by acidic rain water, the metal will corrode. In general it is advisable that steel which is to be encased in concrete, especially for industrial plants, should... 

Plants and animals are themselves highly effective chemical factories and they synthesize many carbon compounds useful to man. These include sugars, starches, plant oils and waxes, fats, gelatin, dyes, drugs, and fibers. 

Loss prevention. Walking around many chemical factories will reveal obvious sources of energy loss, probably the most noticeable being leaky steam valves. Good housekeeping can do much to conserve energy. 

The Perkin family soon bought a rural property near a canal northwest of London, far from the city s new antipollution regulations. At this point, few of William Henry s friends or relatives had so much as glimpsed the inside of a chemical factory. Perkin s knowledge of manufacturing came only from books, but his ignorance was not a serious drawback. Because no one had ever built the kind of equipment he needed or planned such a chemical process before, there was little to imitate. 

Ironically, despite all this scientific progress, modern fiberoptic cables went into service during a decade of chemical catastrophes more reminiscent of the old Leblanc factories than of optical fibers superpurity. On December 3, 1984, a cloud of deadly methylisocyanate gas leaked from a Union Carbide plant in Bhopal, India the gas killed more than 3000 people and injured up to 25,000. Two years later in Europe, a Sandoz chemical factory spilled 30 tons of chemicals into the Rhine River, killing fish for 120 miles downstream. In North America, the Exxon Valdez oil tanker spilled crude oil over 1000 miles of Alaskan coastline in 1989. 

The public was outraged. It did not matter whether the pollution came from a chemical factory, power utilities, mines, petroleum, automobiles, or semiconductors the chemical industry s reputation was in free-fall. In 1990, the U.S. Congress established the Super Fund, requiring industry to pay for cleaning up hazardous waste. Major chemical manufacturers banded together in a voluntary effort to reduce factory emissions to almost zero and to police themselves. At the opposite extreme, some environmentalists called for the elimination of all toxic substances.

Even though some nitroaromatic compounds are purposefully spread in the environment as pesticides, the majority of their environmental releases are accidental. For example, in the United States alone, 5.1 tons of nitrobenzene were released in soil in 2002 [65]. The greatest known industrial releases have occurred in China in 2005, an explosion at a chemical factory resulted in the accidental release of 100 tons of benzene and nitrobenzene to the Songhua River [66]. 

As shown in Table 5-1. only people living near chemical factories or work sites are likely to be exposed to measurable amounts of acrylonitrile in air and water. Dispersion modeling studies have indicated that approximately 2.6 million people living within 30 km of emission sources may be... 

Your kindness, with which I am familiar, encourages me to contact you with the request that I be permitted to move with my family to an appropriate apartment at my residence and place of birth, Wola, and to obtain permission to work in the industrial plant Wola, of which I am a part owner, in order to be able to exist. As my son is ill in the hospital, I respectfully request that it be rendered possible for him to receive monthly payments cm his credit account with the chemical factory Wola. The same for my daughter Hanna, who has a substantial credit with the chemical factory Wola. Hoping that you, dear sir, will conform to my wishes. , .
